How does autonomous driving become a reality? The answer lies in the Release 16 5G NR-based C-V2X technology, which will bring direct communication capabilities to advanced autonomous driving cases, such as high throughput and URLLC (ultra-reliable low-latency communication), and Release 14 C-V2X complement each other and provide services for the car.
Designed to ensure safe driving The Rel-14 C-V2X is designed for low-latency direct communication, allowing direct communication between vehicles (V2V) without direct network coverage or access to cellular networks, and direct communication between vehicle pedestrians ( V2P) or communication between the vehicle and the road infrastructure (V2I).
The Rel-14 C-V2X has always been supported by ecosystems and is likely to be an important technology for improving driving safety. Today, leaders in ecosystems such as AT&T, Qualcomm, Ericsson, Audi, Ford are conducting C-V2X field testing, and It is ready to begin commercial deployment of Rel-14 C-V2X in 2019, and at the same time, lead the evolution and upgrade of C-V2X technology based on 3GPP Release 16 5G NR, which supports autopilot use cases. Just like Rel-14 C-V2X direct communication can Relying on cellular networks, the Rel-16 5G NR-based C-V2X direct communication technology also does not require cellular network coverage.
Self-driving cars rely on several different types of sensors (such as radar and camera systems) to detect and infer their surroundings and road conditions, but these sensors are limited by line-of-sight (LOS) operations.
The Rel-14 C-V2X direct communication compensates for the shortcomings of these sensors by providing 360-degree non-line-of-sight (NLOS) sensing capabilities, extending the vehicle's ability to detect on the road even in blind spots or in inclement weather conditions. Help drivers better predict and make decisions.
The R--16 5G NR-based C-V2X direct communication technology will take non-line-of-sight sensing capabilities to new heights. The high throughput and URLLC capabilities of the 5G NR C-V2X technology will enable autonomous vehicles to communicate directly with the aircraft in an efficient manner. Other vehicles or share their perception of road conditions, road conditions and the environment with the road infrastructure. These functions are designed to help them model the surrounding real environment by sharing high-throughput sensor data between vehicles.
In addition, with 5G NR C-V2X technology, vehicles can interoperate with their intentions and planned actions, and plan for a more scientific autonomous driving path with better predictability and decision. With the help of the C-V2X car network, you can Stay away from congested roads and say goodbye to traffic jams.
The 5G NR-based C-V2X technology also enables autonomous vehicles to more accurately understand their location through real-time local updates, such as 3D HD maps, and become more familiar with the surrounding environment.
